R8C/32C Group
Figure 3.1 is a Memory Map of R8C/32C Group. The R8C/32C Group has a 1-Mbyte address space from addresses
00000h to FFFFFh. The internal ROM (program ROM) is allocated lower addresses, beginning with address
0FFFFh. For example, a 16-Kbyte internal ROM area is allocated addresses 0C000h to 0FFFFh.
The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. The starting address of each interrupt
routine is stored here.
The internal ROM (data flash) is allocated addresses 03000h to 03FFFh.
The internal RAM is allocated higher addresses, beginning with address 00400h. For example, a 1.5-Kbyte internal
RAM area is allocated addresses 00400h to 009FFh. The internal RAM is used not only for data storage but also as
a stack area when a subroutine is called or when an interrupt request is acknowledged.
Special function registers (SFRs) are allocated addresses 00000h to 002FFh and 02C00h to 02FFFh. Peripheral
function control registers are allocated here. All unallocated spaces within the SFRs are reserved and cannot be
accessed by users.
